IMPROVEMENT IN SEATS FCR RAILWAY-CARS.

Speciiication forming part of Letters Patent No. 128,428, dated June 25,1872.

Specification describing a certain Improvement in Seats forRailroad-Cars, invented by PHILIP I. SCHOPP, of Louisville, in thecounty of Jefferson and State of Kentucky.

rlhe invention relates to the combination of so-called air-cushions withthe frame and ordinary cushions of car-seats, as to form an elasticmedium between the frame of the seat and the cushion proper. The objectis to give more elasticity to the seat, and neutralize the vibratingmotions experienced when the train is in motion.

Figure 1 is a plan of the frame of the seat with the air-cushionattached. Fig. 2 is aplan of the upper frame of a seat, with grooves forthe reception of the air-cushion-viewfrom below. Fig. 3 is a verticaltransverse section of a seat. Fig. 4 is an isometrical view, showingpart of the lower frame, air-cushion, upper frame, and bottom board'.

A is the lower frame of the seat, resting on a pedestal on one` side andon a side-board, H, on the other. It is constructed in the usual f wayand providedwith half-circular grooves.

In these grooves the air-cushion B is fitted. This air-cushion is madeof elastic material with a hollow space inside, lled with air andhermetically closed. It may be of avcylindrical (as shown in thedrawing) or 'anyfothcr form as suits best. It is to be provided withperforated iianges or side projections to be fastened to the lower frameA. On this air-cush ion it is intended to rest the upper stuffed part ofthe seat; for this purpose frame G is also provided with grooves D,forming, however, a segment only of the lower circle, so as to compelthe upper part or cushion proper to rest on the air-cushion only, andnot touch the lower frame A; in otherrespects these grooves have tocorrespond With the lower ones. The upper frame C is, by means of thevertical projections on aircushion B, loosely attached io frame A, asshown in Fig. 4. G represents part of the side wall of a car; E, thestuling of the seat; and F, the bottom board of the same.

I claim as my invention- The combination of part A, air-cushion B, andpart C, substantially as and for the purpose hereinbefore set forth.
